Good question but every article I could find on the Ariel Atom Aero-P
completely omits any discussion of the powerplant, focusing instead on the dual
electric fans it uses for on demand down force. They claim it can be visibly
seen to compress the suspension when engaged and can be used for launching or
cornering to significantly aid in adhesion to the track without requiring the
wing/winglets and such that actually consume extra fuel by virtue of the
aerodynamic drag such downforce devices use to achieve extra downforce, which
also only occurs "at speed".

It's currently just a prototype but it's use of a race proven (and immediately
banned!) idea is cool. Jim Halls team first ran a car utilizing this concept in
their Chapparal Can Am car in 1970, but McLaren instantly lobbied for its
banning from the series. Niki Lauda later ran a similarly designed F1 car, which
was also banned.

In the 90s toy maker Tyco incorporated a variation on this theme by placing the
electric motors magnets in their HO series slot cars in close proximity to the
rails in the track thus utilizing magnetism for highly increased cornering
capabilities. The track adhesion was so good they could even be run upside down.
Lil bitches were also capable of 1000 scale miles per hour on long straights!

If your toy will be parked on the street and only get used every second weekend
then make sure it has a hardtop.
I have had a car and a bike for many years and due to the cost of registration
and insurance the happiest I have been was when I had a dodgey 10 year old car
and a new bike every second year. This was affordable. Now I am older I register
and insure a car only (V8 of course) and it cost me the same. So if you can
afford it do whatever but the best bang for your buck is to have 1x cheap
rego/insurance & 1x expensive rego/insurance.
2x expensive rego/insureance will make you sell it eventually.
2x cheap rego/insurance won't provide a fun car.
